i Specification of Letters Patent.

Patented May 1, 1906.

Application iiled July 17, 1905. Serial No. 270.051.

1"0 a/ZZ whom, it may concern: I

Be it known that I, FRANK LA BARE, of

I Owatonna,-Stee1e county, Minnesota, have invented certain new and useful Improvements in Ohurns, of which the following is a specification.

My invention relates to combined churns and butter-workers; and the object of the invention is to provide means for allowing the buttermilk to drain off and escape from the churn during the operation of working the butter.

AThe invention consists generally in. providing means for locking the churn-door in a nearly but not entirely closed position, leaving a narrow crack between the door and its seat for drainage purposes.

Further, the invention consists in various constructions and combinations, all as hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, forming a part of this specification, Figure l is a perspective view of a portion of a churn and cover or door with my invention applied thereto. Fig. 2 is a transverse sectional view. Fig. 3 is a detail sectional view on the line y y of Fig. 2, showing the door in a partially but not entirely closed position. Fig. 4 is a similar view showing the door in its closed position. n

In the drawings, 2 represents a churn having the usual opening 3 and a casting 4 eX- tending around the edge of said opening and provided with a seat 5 for a gasket 6. A door 7 is hinged on one side of said opening, preferably by means of the hooks 8, engaging spring-straps 9, secured to the churn. Bolts 10 have threaded ends passing through the 1 straps 9 and provided with nuts, by means of which the straps and the hooks can be drawn down toward the churn to increase the pressure of the door on the gasket. Cam-levers l1 are mounted on the churn on the side opposite the hinges and at each end and are adapted to bear upon the cover and lock it rmly in its closed position during the churning operation. It is desirable during the working of the butter to leave the door open a little for drainage purposes, and at the same time it is necessary to secure the door to prevent any possibility of its escaping from its fastenings and openin wider than Was intended. I therefore provlde plates 12,

l slidably secured on the edge of the door oppof `site its hinged side by means of pins 13, passing through slots 14 in said plates and into' the edge of the door. Handles 15 are pro,-A

vided on said plates to permit their conven.-

ient lengthwise movement. Each plate is provided in its lower edge with a recess 16, which 1s adapted to coincide with a lug 17 when it is desired to entirely close the door.

Whenever the l operator wishes to lock the door in a partially-closed position, the plates are moved, as shown in Fig. 3, so that when the door is closed the lugs 17 will notcoincide with their recesses, but engage the plates at one side thereof and prevent the door from being entirely closed. The cam-levers are then swung round to their closed position, pressin the door down firmly upon the lugs 16 and eavin a crack between the door and its seat of su cient width to drain the churn during the butter-working operation. Whenever desired, the cam-levers may be-loosened the plates moved to a position to allow the lugs to enter the recesses therein, and then the door may be entirely closed. The depth of the slots 16 and the hei ht of the lugs 17 will regulate the width of t e crack between the door and its seat, it being only necessary to provide sufficient space or clearance to secure the ldesired drainage. I have shown separate plates provided at each end of the churn-door; but they may be connected or formed in one piece, if preferred. The handles for operatinon the plates may also be used in opening and e osing the churn-door.

I claim as my invention- 1. The combination, with a churn and butter-worker provided with an opening and a door therefor, of means arran ed to temporarily prevent the complete c osing of said door leaving a narrow crackbetween it and its seat, and means for locking said door in its nearly but not entirely closed position.

2. The combination,with a churn and butter-worker having an opening and door therefor, of sliding means mounted on said door, means mounted on the churn in thepath of said sliding means to engage the same and prevent the complete closing of said door, and means for locking the door in its nearly but not entirely closed position.

3. The combination, with a churn and butter-worker having an opening and a door therefor, of a plate having a recess mounted IOO on said door, a lug provided on thechurn to enter said recess, said plate being movable to prevent said luv' from entering said recess,

and means for ocking said lug in engagement with said plate and said door in its partially-closed position, substantially as described.

4. The combination, with a churn and but-- ter-Worker having an opening and door therefor, of plates slidably mounted on said door and having recesses in their edges, lugs provided on the churn and adapted toenter saidrecesses and allow the complete closing of said door or engage said plates at one side of said recesses and prevent the complete closing of said door, and cam-levers arranged to engage said door and lock it in its nearly but not entirely closed position.

5. The combination, with a churn and butterworker having a door-opening and door therefor hinged at one side of said opening, of plates 12`slidably mounted on the edge of said door opposite from said hinges and provided with recesses in their lower edges, lugs 17 provided near, the edge of said vopeningl and adapted to enter said recesses and allow the complete closing of said door and engage the lower edge of said plates when they are -Inoved lengthwise on said door and prevent the complete closing of the same, and camlevers arranged to engage the top of said door and lock it in its closed or partially-open positions, substantially as described.

The combination, with a revolving receptacle provided with a peripheral opening and a door therefor, of means arranged to temporarily prevent the complete closing of said door leaving a narrow crack between it and its seat, and means for rigidly securing said door in its closed position or in its nearly but not entirely closed position.

7. The combination with av churn and butter-worker provided with a door and opening therefor, of means for temporarily locking said door in a partially-open position leaving a narrow crack between it and its seat and preventing it from moving in either direction, i
